IMPROVEMENT IN MACHINES FOR ERECTING FRAME STRUCTURES.

Specification forming part of Letters Patent No. 207,746, datedSeptember 3', 1878; application filed June 13, 1878.

To all whom it may concern! Be it known that I, SUMMIT R. KING, ofMason, in the county of lngham and State of Michigan, have inventedcertain new and useful Improvements in Machines for Erecting FrameStructures; and I do hereby declare that the following is a full, clear,and exact description thereof, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which- Figure 1 is a side elevation. Fig. 2 is a front view. Fig.3 is a rear elevation of the lower part of the swinging crane forraising plates and purlin-bents, which is used in combination with andforms a part of my invention 5 and Fig. 4 is a side view of the same.

Similar letters of referenceindicate corresponding parts in all thefigures.

This invention relates to devices for erecting the frames and bents ofstructures, having for its object to save time, labor, and avoid thedanger incident to the usual method of raising the bents by ordinarycranes and tackle; and it consists in an improved construction andcombination of parts, substantially as hereinafter more fully described.

In the drawing, AA are the bottom planks, B B the uprights, and G O thebraces. The upper parts of the standards B B are united and strengthenedby the cross-braces b b and the cap-piece or beam 0, upon which thesheave or pulley a is suspended. d d are two blocks, in which thejournals of the hoisting-drum D are pivoted, and which also serve as arest'or support for the cap-beam 0. These blocks are grooved or recessedon their under side to make room for the brace-rods e e. ff are verticalbrace-rods, which extend from the bottom pieces,A A, up to drum D,around the shaft or axle of which their ends are bent, so

as to form hooks, by means of which the upper and lower parts of thestructure are firmly bound together.

Drum D is operated by a crank, g, and for the convenience of the menworking the machine a foot-board or platform, h, is placed on one sideof the machine a suitable distance below the crank. The hoisting-rope 45passes from drum D through the sheave or pulley a,

and up around pulley a, which is suspended upon the cap-beam c, and thendown through another pulley, afl'and up again to a rod or cross-piece,0, below the cap-beam, to which its end is secured. The sheaves a and aare united by a short chain, k, which forms a rest for the posts oruprights of the bents to be raised, as hereinafter described indescribing the operation of the machine.

l is a ratchetwheel, secured at one end of drum D, which engages with apivoted keeper, m, so as to prevent the drum from turning in the wrongdirection and keep the bend or frame, during the operation of hoisting,in any given position when the crank is released. A pawl-and-ratchetattachment may be substituted for the wheel 6 and pivoted keeper m.

Two of these machines, both constructed exactly alike, are used inerecting a frame, one being placed at each end of the bent by placingthe bottom timbers, A A,'across the sill, a block, E, being placed underthe front part, and another similar block, F, under the rear part, ofthe machine, after vwhich the heel of this is fastened down upon thesill by means of the clamp-block H.

G is a block, which is placed in front of the machine for the uprightsor posts of the bents to rest against. The two end, posts of the bent tobe raised are secured'in the chains k, the same distance from the footof the posts as the height of the machines, after which the bent israised into a vertical position by turning the cranks of thehoisting-drum's, so that both ends or sides of the bent shall be raisedevenly.

To place the purlin bents and plates in po- 'sition I employ a T-shapedcrane,'which consists of three parts-win, an upright tilting beam, I,having at its top an arm or crosspiece,'K, and a wedge-shaped block, L,pivoted to its lower end.

Arm K has a sheave, 0 0', at each end, and is firmly secured to theupright I by braces 10 p. The lower end of the stem or upright I has aseries of perforations, 1' r r, by means of which this upright may bepivoted adjustably upon a pin, g, projecting from the lower pointed endof the wedge-block L.

M is a keeper, made of iron, which spans the face of the upper wide partof block L, and

through which the upright I is passed. This keeper will control themotion of upright I and prevent it from swinging too far in eitherdirection. Upon the back part of block L is bolted two stout iron bars,bent at the top to form hooks s s, the edges of which are sharpened andform one side or part of a clamp, the other part or jaw of which isformed by a rod, t, which slides in a groove or recess formed in themiddle of block L, and terminates at its lower end in a pointed hook, t,while its upper end is screw-threaded and passes through a nut, n, whichworks against a plate, 22, bolted upon the top of block L, across thegroove in which the rod or bolt 15 is inserted and slides, and whichsaid plate is perforated to allow the screw-threaded end of bolt 15 topass through.

This part of my invention is used as follows After the bents have beenerected and secured, so as to form the frame without the roof, thefastening block or clamp H is shifted from the heel to the front part ofthe machine, as shown in Fig. 2, for the purpose of preventing motionlaterally by firmly anchoring the front part of the machine, whichcarries the hoistin g-tackle, upon the sill. Next, block L is clampedupon the top cross-piece or beam of the end bent, near the end-post, byclamping the beam between the hooks s s t, so as to hold block L, whichcarries the swinging crane I K firmly in place. Upright I having beenproperly adjusted (according to the height the roof is to have) in blockL, by means of the perforations 'r and pin g, the hoisting-rope w isremoved from pulleys c a and passed direct from the drum through sheave0, across arm K from one end to the oth er, and down through sheave 0',after which the end is secured to the plate or purlin-bent which is tobe raised and placed in position. As in the case of the cranes forraising the bents, two of these purlin-cranes are used, one at each endof the frame, and the plate or purlin-bent is raised by turning thecranks of drums I) (one on each side) in the same manner as raising thebents.

By the use of my invention the frames of barns, dwelling-houses, orother structures, may be raised safely and expeditiously, requiring theassistance of only a few hands. It saves time, labor, and expense, andavoids danger to life and limb, as in cases where ordinary tackle isused, resulting frequently in accidents to the workmen and damage to thestructure.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. The machine for raising thebents of frame structures herein described, consisting of thecrane-frame A A, B B, G 0, having brace-rods e 0 ff, crossbraee b I),and cappiece 0, in combination with the hoisting-drum D, rope 20, andpulleys a a a the two last of which are united by the chain-rest 7r,substantially as for the purpose herein shown and described.

2. The combination of the swinging upright I, having cross-piece K,carrying the pulleys 0 0, with the wedge-block L, having keeper M andpivoting-pin g, substantially as and for the purpose herein shown anddescribed.

3. The wedge-shaped clamp-block L, provided on one side with the keeperM and pivot g, and on the other with the stationary clam ping-hooks s 'sand adjustable sliding bolt t, having clampinghook t, substantially asand for the purpose herein shown and described.

4. The combination of the hoisting frame A A, B B, O 0, having drum 1),with the adjustable tilting frame, consisting of parts I K L, andhoisting-rope w, all constructed and combined to operate substantiallyas and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as my own I have hereto atlixedmy signature in presence of two witnesses.

SUMMIT R... KING.
